Contras
No work-life balance, study 14 hours a day like your life depends on it. Army-like distance from some of the mentors. Not much mental support if you are slower than others - some of my friends left the program feeling they are lesser then others. I strongly recommend to join the program with a positive attitude, strong prepared mentality, and don't compare yourself to others.
